Using AfxMessageBox

Question

How to display an double variable using AfxMessageBox or other similar?

Answer 1

There are many ways to construct a string for display but in an MFC environment it is common to do something like

CString strMsg;
double dblVar = 100.00;

strMsg.Format(_T("Double value is %f"), dblVar);
AfxMessageBox(strMsg);

Answer 2

Internally CString::Format probably uses _fcvt_s and I think it is a matter of personal preference what you use. CString::Format at least is easier for the programmer.

See Convert double to char and How to convert double to string in VC++.

My Formatted MessageBox might be a useful a bit.
